Electric Power
Power \(\:(P)\:\) is the rate of doing work and is measured by the amount of foot pounds of work done in a particular unit of time. A horsepower is a measure of power.
Electric Power (Watt) formulas
\(\large{ Watts = \frac{Volts^2}{Ohms} = P = \frac{V^2}{R} }\) | |
\(\large{ Watts = Volts^2 \; Ohms = P = V^2 \; R }\) | |
\(\large{ Watts = Volts \; Amps = P = V \; I }\) | |
\(\large{ W = \frac{ m \; g \; h }{ t } }\) | (horsepower) |
Where:
\(\large{ P }\) = power
\(\large{ I }\) = current
\(\large{ h }\) = height
\(\large{ m }\) = mass
\(\large{ R }\) = resistance
\(\large{ g }\) = gravitational constant
\(\large{ V }\) = volt
